The new Biofit HD matrices are stiffer than traditional clear matrices which makes them easier to place, and the new shape makes them appropriate for 75% of all posterior molar cases and ensures ideal tooth contours.

The A-102 Incisor-Distal Matrix, is used for upper lateral and central incisors and both sides of canines.
For large or deep composites, these Bioclear anterior matrices are hands free and can be used without an interproximator if the contact is intact. In other words, the matrix fits so intimately that the pressure of the gingiva can seal the gingival margin. However, to assist in creating a snug contact by tooth separation, the Standard Interproximator can be used after the initial increment of flowable is placed.

This 10mm matrix is a more open matrix allowing easier access but is less anatomically adapted on the facial and lingual. The A-104 is the best choice for lower incisors, and can also be used upside down (tab facing the gingival) for restoring the incisal third when you need to “reach out” to close the incisal contact. These teeth often have little or no curvature in the gingival half of the tooth, a problem unique to many lower incisors.
